Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
How many grounding clamps are permitted on one ground rod?
As long as the clamp is of an approved type only one is needed per ground rod.
If a dryer has a green ground wire that was connected to the green wire on the 4 prong cord what do you do with the green wire now that you have a 3 prong cord?
In a nutshell, you need to connect your green grounding wire to the white grounded conductor (that originates in your existing 3-wire dryer receptacle that does not have a green grounding conductor).My answer assumes that you are in the United States. If not, the information below may not apply. In 1996, the U.S. National Electrical Code implemented a new rule that no longer allowed the grounded circuit conductor (white neutral wire) to serve as the grounding conductor (green wire) for many household appliances. New installations of ranges and clothes dryers must have a separate green or bare grounding conductor.Now, there is an exception for existing installations. I have put BOLD emphasis on parts that may apply to your question. The text in brackets [ ] is not part of the NEC but explanations added by me.NEC Article 250.140 Exception: For existing branch circuit installations only where an equipment grounding conductor [green wire] is not present in the outlet or junction box, the frames of electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers, and outlet or junction boxes that are part of the circuit for these appliances shall be permittedto be connected to the grounded circuit conductor [white neutral wire] if all the following conditions are met.(1) The supply circuit is 120/240-volt single-phase, 3-wire; or 208Y/120-volt derived from a 3-phase, 4-wire, wye-connected system.(2) The grounded conductor is not smaller than 10 AWG copper or 8 AWG aluminum.(3) The grounded conductor [white wire] is insulated, or the grounded conductor is uninsulated and part of a Type SE service-entrance cable and the branch circuit originates at the service equipment.(4) Grounding contacts of receptacles furnished as part of the equipment are bonded to the equipment [any built-in receptacles on your dryer have a ground connection (green wire) to the metal frame of the dryer].In summary, you need to connect your green grounding wire to the white grounded conductor of your existing 3-wire receptacle, provided you meet all 4 of the above conditions.
What does the National Electrical Code NEC say about running separate ground wires?
From the 2011 NEC, Section 250.130 states, in part, "For replacement of non-grounding-type receptacles with grounding-type receptacles...connections shall be permitted as indicated in 250.130(C)." Section 250.130 (C) states in its entirety, "(C) Nongrounding Receptacle Replacement or Branch Circuit Extensions. The equipment grounding conductor of a grounding-type receptacle or a branch-circuit extension shall be permitted to be connected to any of the following: (1) Any accessible point on the grounding electrode system as described in 250.50 (2) Any accessible point on the grounding electrode conductor (3) The equipment grounding terminal bar within the enclosure where the branch circuit for the receptacle or branch circuit originates (4) For grounded systems, the grounded service conductor within the service equipment enclosure" (5) For ungrounded systems, the grounding terminal bar within the service equipment enclosure" Now for some of my thoughts. It sounds like what you got was adequate. It was correct except for he should have used green or bare conductor, not white, unless he used green tape near the end of the conductor to designate it as green. This tape would be inside the box but I would have marked it outside the box also if it is visible. I would have run this conductor as close as possible and preferably attached to the existing circuit conductors. Looping the conductor as you have stated is not the best installation, in my view, but if you have at least 6 inches from the entry of the conductor to the grounding terminal and another 6 inches before it leaves the box, this is ok. The code does not require this 6 inches if the conductor isn't spliced but in your application it should be since, in my view, it should have been spliced. Solid or stranded is of no significance. While I have quoted the 2011 NEC in my answer, I do not expect this has changed any in recent years. The use of the word "bonding" by your electrician was technically incorrect but "bonding" and "grounding" are sometimes used synonymously. They are different but often look alike to the untrained eye. Even electricians often misuse these terms and fail to understand the difference. It takes someone like myself who is a little anal retentive to use the terms properly. I hope you will acknowledge my answer as I am particularly interested to know if you got it.
What causes an electric motor body to give an electric shock when a person touches it and the ground together?
That condition is called a "ground fault". That's when the insulation of the motor winding has a break somewhere, allowing current to leak to the motor housing. The motor SHOULD be grounded, protecting the user from electrical shock, but many older motors were not grounded, providing the potential for just this type of condition. Newer motors are often "double insulated", meaning that not only is the motor winding insulated, the motor housing is also insulated. Often the housing of a double insulated motor is made of a type of plastic.
What is code for electric outlet height outdoors?
Outdoor receptacles shall be installed outdoors so as to be readily accessible from ground or grade level. All outdoor receptacles located within 6 feet of ground or grade level shall be protected by a GFCI (Ground Fault Circuit Interrupter of the class A type.

What are the different kinds of electrical receptacle?
The most common types are the regular type, where the only over current protection is provided by the breaker panel. the other most common type is the GFCI (Ground Fault Circuit Interrupter) This type has a built in "circuit breaker" so when it senses a fault in the circuit it trips-this type is the safest as they are more sensitive than circuit breakers in the breaker panel.See related links below.
What are electrical receptacles?
The terminology in North America it is used for wall outlets. The majority of receptacles used in homes are duplex receptacles. The device consists of one upper and one lower connection point that are rated at 15 amp capacity. The receptacle can be converted to two individual 15 amp circuits by removing a tie bar between the upper and lower connection points. This type of installation has to be connected by a three wire cable.
